A surface lumped circuit model is formulated for the discontinuous Galerkin time-domain modeling of devices with lumped elements. A leap-frog algorithm is used for time integration, resulting in an explicit and conditionally stable time-marching algorithm. A microstrip filter with four ports and two lumped elements is simulated to validate the proposed method.
A fast waveguide port parameter extraction technique for the discontinuous Galerkin time-domain method is described and investigated for the simulation of waveguide-fed devices. Auxiliary differential equations are employed to handle the convolutions involved in the wave port boundary condition, which results in a significant decrease of the computing cost for implementing the boundary condition at...
An efficient algorithm based on the discontinuous Galerkin time-domain (DGTD) method with a hybrid mesh is proposed to simulate electromagnetic problems. To validate the algorithm and demonstrate its efficiency, a spherical cavity and a horn antenna are simulated using hybrid meshes.
In this paper, we explore the accuracy limits of an energy conserved splitting finite difference time domain (EC-S-FDTD) method applied to the Maxwell equations which has recently been proposed to solve the Electromagnetic (EM) problem. The numerical dispersion properties of the EC-S-FDTD methods are investigated. The results of this analysis are useful for the application of the method, and for the...
In order to reduce the dispersion of the conventional HO-FDTD (2, 4) method, the axes-optimized method has been provided. This paper mainly discusses the optimization of the weight parameters based on the numerical dispersion equation. The numerical examples have been given to demonstrate the optimized HO-FDTD (2, 4) method. It has been found that the dispersion error can be eliminated in the axial...
In this paper, a conformal high-order finite difference time-domain (CHO-FDTD) scheme is present to deal with the dielectric curved objects. The general update equations of the CHO-FDTD have been derivated. The CHO-FDTD method, based on the effective dielectric constant EDC technique, is applied in scattering cases, and the conclusion are that the scheme provides the better accuracy than the HO-FDTD...
